I'm working on a document that will have certain sections replaced with user input, and I'd like to make sure that the user input doesn't execute any roff code.
I'm having trouble figuring out how to escape a "." after a newline. Looking at the man pages I thought I could just change all "." after a newline to "\.", and that would escape it, but this doesn't seem to work. I created a tiny 2-line roff input program to show my problem. ----------------foo.t-------------- There are many things I'd like to know about the way that roff works. \.this is a line that starts with a <.> ------------------------------------- I execute groff with groff -ms -Tascii foo.t and this gets written to stderr foo.t:2: warning: macro `this' not defined without the -ms package, the warning is not written to stderr, but the 2nd line still doesn't show up in the output stream. I'm running groff version 1.19.2 Thanks for any advice you can give. mike
